FEEDER FOR meow moLns,

Application filed November 1, 1924. Serial No. 747,328.

1' all whom it may concern:

Be itknownthat we, BLOOMFEELD H. HOWARD and ERNEST J. TURNER, citizens of the United States, residing, respectively, at \Vashington, District of Columbia, and Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new'and useful Improvements in Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in feeders for ingot molds and pertains to the manufacture of iron or steel ingots and has for its object to provide a feeder in which 1 seams and holes known as-piping aregprevented from forming in the ingots and at the same time reduce segregation to a minimum.

The object of our invention is to provide 2 a feeder of this character in which the bore thereof and the bore of the mold are of a shape'to more nearly conform to the shape of the finished product into which the ingot is to be rolled.

A further object of our invention is to provide a feeder for the production of iron or steel ingots that will be of a shape intermediate in form to many of the articles of the finished product; e. g. round and flat could be easily rolled om ingots of the shape designed as could also other shapes still further removed from the original form.

A still further-object of our invention is to provide a simple, feeder of this character having certain de tails of structure and combination of parts hereinafter more fully set forth.

In the accompanying drawings:

Figure 1 is a perspective view of a feeder embodying our invention.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a vertical transverse sectional F'gure 6 is a top plan view of a still further modified form of feeder. 1 1

In the casting of metal ingots it has been found very gots of a shape similar to that of the finmajor and minor cheap and effective view showing the feeder of a reversible top plan view of a modified advantageous to form the in-' ished article into which an ingot is to be rolled and thus prevent the necessity of rolling the ingot under heavy pressure to cause it to assume the shape in which it is to be rolled, into the finished; product.

In order to carry out our invention we provide a feeder for an ingot mold in which the interior bore of the mold and also the interior bore of the feeder are provided with axes and in thus carrying out our invention we have produced an ingot having a major and a minor axis whereby theingot can be readily rolled into a fiat bar or plate with less rolling than as if it were cast with the If on the other hand a circular product were desired the rolling process would be reversed. In rolling aconvex surface, scales will be crushed and dropped off more readily than a flat surface'into which they become more or less imbedded. 1

In carrying out our invention the mold 1 is provided with the feeder 2 having the ribs 3 for supporting it within the upper end of the mold. The minor axis 4 of the bore 5 of the mold is the major axis 6 so rolled into a flat or in a circular form. K

In Figure 2 the major and minor axes are nearly 0f the same length so that finconsiderably less than that the ingot may be rectangular form; also axes of an equal length;

ished articles of circular or curved forms could be easily rolled.

In Figure 3 we have shown a flange 7 extending entirely around the feeder intermediate the ends, so that the same can be reversed in the mold. In this form the ma- ]01 and minor axes of the bore of the mold are the same as that shown in Figure 2.

In the modification shown in Figure 4 the minor axis 8 is greatly reduced and thus a flat plate can be readily rolled from the ingot cast thereby.

In the modification shown in Figure 5, the major and minor axes are of the same length as in Figure 4, but we have shown the feeder 9 having its outer wall fluted as at 10. In this form the bore of the mold would be fluted to correspond with the fluted wall 10 of the "feeder.

In the modification shown in Figure 6 we have shown the feeder 11 having the minor axis l2 less than that shown in Figures 4 and 5 whereby the flat plate can be readily rolled from an ingot cast thereby.

Having thus fully described our invention what we'claim is 1. A feeder for ingot molds comprising a body portion of a general elliptical contour with a bore therethrough having a major and aminor axis.

2. A feeder for ingot molds comprising a body portion of a general elliptical contour with a curved bore having a major and a minor axis.

3. The combination with an ingot mold ot'a general elliptical contour having a. bore with a major and a minor axis, and a feeder of similar shape supported by the mold and having a major and a minor axis.

4. A feeder for ingot molds comprising a body portion of a general elliptical contour having supporting means carried on its outer face and the bore of the feeder having a major and a minor axis.

5. The combination with an ingot mold of a general elliptical contour .havinga major and a minor axis, and a feeder of similar shape adapted to enter said mold,

and having means supporting it on the mold, said feeder having, a bore extending therethrough with a. major and a' minor axis.

6. A feeder of a general elliptical contour for ingot molds adapted to nest upon the upper end of a mold of similar shape-and having a major and a minor axis.

7. A feeder of a general elliptical contour for ingot molds adapted to be supported upon the upper end of a mold of similar shape and having a major and a minor axis.

8. A feeder of a general elliptical contour for in ot molds adapted to be suspended within the upper end of a mold of similar shape and having a major and a minor axis.

'9. A feeder of a general elliptical contour for ingot molds adapted to be supported and reversed within the upper end of a mold of similar shape, each having a major and a minor axis.

10. A feeder of a general elliptical contour for ingot molds adapted to be used in the nxruufacture of iron and steel and having a major and a minor axis.

11. A feeder of a general elliptical contour for ingot molds adapted to be used with an ingot mold of similar shape in the manufacture of iron and steel ingots, each having a major and a minor axis.

12. A feeder for ingot molds having a body portion of a general elliptical contour-with corrugations on its outer wall and having a major and a minor axis.

13. A feeder for ingot molds having a body portion of a general elliptical contour, of the extrememathematical limitations of any ellipse relative to a major and a minor axis.

In testimony whereof we aflix our signatures.
